Not quite fixed -- EN 6.25 works when reinstalled, after deleting the database, but all the Tags and Notebook names are missing, and customizations are missing too.
Then, separately, 10.7.6 stopped working, and upon reinstalling, each time there is an update, it forces an uninstall of 6.25.1.
So far, this whole revision of EN code has done nothing worthwhile for my use, except 10.7 doesn't hang as often as 6.25 and earlier did, but it has been a constant problem for my use. I keep hoping that eventually they will bring out something new really useful, a la Roam or Obsidian, but there is no hint that is in the future.
If EN weren't so integral to my daily use, with over 60,000 notes to date, I would abandon it.
Right now I'd settle for the time being if I could customize the keyboard shortcuts, like can do in 6.25.
